Early in the show, Ross jokes about an interview planned with Sachs telling Brand that "I had a go on his daughter" would be "the sort of thing you'd say".

Brand replies that he knows Sachs' granddaughter - 23-year-old Georgina Baillie - and says she has visited his home and that she is a member of "a baroque dance group called the satanicsluts.com".

He continues: "She always said to me, 'don't mention that to my granddad Manuel', and now here we are.

"So when we talk to Manuel, don't mention that his granddaughter's a satanic slut."

After it emerges that Sachs will not now be on the show due to unforeseen circumstances, listeners hear Brand and Ross leave four messages on the actor's voicemail.

Here are extracts from those messages:

Message one:
As Brand begins to leave a message, Ross blurts out: "He fucked your granddaughter... I'm sorry I apologise. Andrew, I apologise, I got excited, what can I say - it just came out."

Jonathan Ross is the BBC's highest-paid entertainer

Brand replies: "Andrew Sachs, I did not do nothing with Georgina - oh no, I've revealed I know her name. Oh no, it's a disaster."

Ross goes on to say: "If he's like most people of a certain age, he's probably got a picture of his grandchildren when they're young right by the phone. So while he's listening to the messages, he's looking at a picture of her about nine on a swing..."

Message two:
"Andrew, this is Russell Brand. I'm so sorry about the last message, it was part of the radio show - it was a mistake."

Ross adds: "It might be true but we didn't want to break it to you in such a harsh way."

According to the BBC Trust report, the show's producer - a BBC employee "on loan" to Brand's firm Vanity Projects - was "shocked" by the initial exhange, but decided to resolve the issues with the content at the show's editing stage.

Andrew Sachs was, at the time, at the BBC's Maida Vale studios recording a Sherlock Holmes mystery. He heard some of the material on the answerphone, although not all of it. He managed to contact the studio, but says he was told it was too late to be put through to Brand and Ross.

Jonathan Ross says he said the material could only be included with the consent of Sachs and Baillie. Brand is thought to have left a voicemail message for Baillie apologising for what he had said to her grandfather.

THURSDAY 16 OCTOBER

The show's producer telephones Andrew Sachs. Their accounts of the conversation differ. The producer said Sachs gave his consent to broadcast, Sachs said he demurred. Both said the content needed toning down.

They also discussed a future appearance on the programme - Sachs believing this would be in place of the material already recorded.

"No steps appear to have been taken to obtain informed consent from Ms Baillie," the Trust says.

The producer wrote to Radio 2's head of compliance, David Barber, highlighting the issues with the calls.

"Andrew Sachs AKA Manuel is aware of it and happy... it makes for some brilliantly funny radio. Russ and Jonathan both VERY keen for it to go out."

Mr Barber listens to the material twice and e-mails Radio 2 controller Lesley Douglas recommending it is aired with a warning.

FRIDAY 17 OCTOBER

Ms Douglas sends a one-word reply to authorise transmission of the material: "Yes.".

She told the trust her head of compliance had "never got it wrong before".

SATURDAY 18 OCTOBER

The show is broadcast between 2100 and 2300 BST. It opens with this warning: "The next programme contains some strong language which some listeners may find offensive."

The producer had not submitted a compliance form, and the show had not been listened in full and signed off by a Radio 2 executive, in breach of BBC rules.

SUNDAY 19 OCTOBER

Two complaints are received about the programme - one referring directly to the material about Mr Sachs.

WEDNESDAY 22 OCTOBER

Sachs' agent Meg Pool is alerted to the contents of the broadcast when a journalist for the Mail on Sunday phones her for a comment.

Sachs was taunted about Brand's alleged liaison with Georgina Baillie

She and Sachs listen to an online recording of the show which leaves the actor "offended very much indeed".

Also on Wednesday, in an interview with the BBC to promote his new football book Articles of Faith, Brand says: "I'm really enjoying the Radio 2 show.

"I did the last one with Jonathan Ross. He said the f-word and got us into a lot of trouble.

"But when working with any experienced broadcaster like Jonathan Ross, you fly by the seat of your pants - that's often the nature of it."

THURSDAY 23 OCTOBER

Ms Pool e-mails and writes to Radio 2 controller Lesley Douglas asking for an unreserved apology.

SATURDAY 25 OCTOBER

Brand apologises on his radio show for offending Sachs saying "you mustn't swear on someone's answer phone" but adding that it was "funny".

Recording of Ross's chat show, due to take place on Wednesday evening, is duly cancelled.

Mark Thompson suspended Jonathan Ross

1300 GMT:
Russell Brand tells reporters outside his London home: "It would be silly of me to speak without thinking, because that's caused all this trouble in the first place. I am sorry that I upset Mr Sachs."

1350 GMT:
Andrew Sachs tells reporters he is "not surprised" to hear of the stars' suspension. Asked if he was going to take the matter up with the police, he says: "I'm not going to take it anywhere, I'm not out for revenge."

1730 GMT:
Georgina Baillie says she is "thrilled" to hear Jonathan Ross and Russell Brand have been suspended. In an interview published on the Sun's website she says: "Me and my grandad are both really happy."

Director general Mark Thompson admits to MPs that "a very serious editorial lapse" had occurred. BBC Trust chairman Sir Michael Lyons denied the corporation had been slow in its response to the incident, but admitted lessons could be learned.

Ross and Brand's calls to Sachs were a "deplorable intrusion with no editorial justification", the BBC Trust says after publishing a report into the incident.

It adds a list of high-risk radio programmes should be put together to help prevent a repeat of the incident.

It also recommends tougher penalties for staff who do not comply with editorial guidelines, and that there should be tighter controls on shows made by companies owned by their performers.

The trust also upholds complaints about an edition of BBC One's Friday Night With Jonathan Ross from May, in which which Ross swore in conversation with actress Gwyneth Paltrow and TV personality Michael Aspel.
